Answer:

D).  -5(x + 2)^2 - 2.

Step-by-step explanation:

Parabola which Opens down and vertex (-2, -2) is :

f(x) = a(x + 2)^2 - 2 where a is negative

Stretch by factor 5 gives:

-5(x + 2)^2 - 2.

Choose the statement beloe that lists the sides in order from Least to Greatest.
kolezko [41]

Option A: SU, TU, ST is the right answer

Step-by-step explanation:

In a triangle

  • The largest side and the largest angle are opposite to each other
  • The shortest side and the shortest angle are opposite to each other.

So using the above axioms we can observe the triangle.

  1. The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest
  2. The smallest angle is m∠T = 25° so the shortest side is SU
  3. The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°

So the sides in order from least to greatest are: SU, TU, ST

Hence,

Option A: SU, TU, ST is the right answer

PLEASE HELP! ITS URGENT!
denis-greek [22]

Adding some constant k to a function f(x) has the effect of <em>shifting the graph of the function up by k units</em>. To find what k is, we can pick one point on f(x) and see how far up it's been shifted on the graph of g(x). Looking at the point (0, 2) on f(x), we notice that the point at the same x-coordinate on g(x) is (0, 5) - it's been shifted up 3 units (since the distance between 2 and 5 is 5 - 2 = 3), so we can say that g(x) = f(x) + 3, making k = 3.

Can someone please tell me what the are the measurements of the numbered angles below? And please show your work on how you got
Alja [10]

Answer:

  • ∠1 = 90°
  • ∠2 = ∠3 = 42°
  • ∠4 = ∠5 = 48°

Step-by-step explanation:

The diagonals of a rhombus bisect each other at right angles, and they bisect the vertex angles of the rhombus. Opposite angles of the rhombus are congruent. That means ...

  ∠1 = 90°

  ∠4 = ∠5 = 48°

  ∠2 = ∠3 = 90° -48° = 42°
